Answer:
<h2>
y = -¹/₄x - 1</h2>
Step-by-step explanation:
If two lines are perpendicular then the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 4x - 2 ⇒ m₁=4
4×m₂ = -1 ⇒ m₂ = -¹/₄
The line y=-¹/₄x+b passes through point (4, -2) so the equation:
-2 = -¹/₄×4 + b must be true
-2 = -1 + b
b = -1
Therefore equation in slope-intercept form:
y = -¹/₄x - 1

Step-by-step explanation:
Answer:
Step-by-step explanation:
V = 1/3 pi r^2 h
r = d/2
r = 6/2 = 3
h = 4.5
V = 1/3 *3.14 * 3^2 * 4.5
V = 1/3 * 3.14 * 9 * 4.5
V = 1/3 * 127.17
V = 42.39
